Upgrade to dropwizard 4.0.x

[vermahim]

This repo is currently using Dropwizard 2.0.x which is already 2 years old and is end of life.
In addition to missing out on features, the older version contains a few security vulnerabilities also.

We should migrate to the Dropwizard 4.0.x

Migration path to 3.x would be easier

[vermahim]

How much easier? Do you mean we should follow a 2 step process to move to 4.x ( 2.x -> 3.x -> 4.x )?

4.x is a different rewrite with removal of javax dependencies. This would have ramifications across. Would work on J17 and 3.x upgrade for now. 3.x would not break many things in terms of code.
